What are 2 reasons for a species to become threatened or endangered?

Usually a change or restricting a habitat will cause a species to become threatened or endangered. Also -- when new predators are introduced or old ones become more powerful, native species are threatened.

IMPOACHING BY HUMAN AND DUE TO DEFORESTATION.

You're welcome! I'm glad I could help. Additionally, besides habitat loss and introduction of new predators, there are several other factors that can contribute to a species becoming threatened or endangered. Here are a few more reasons:

1. Overexploitation: When a species is hunted or harvested at an unsustainable rate, its population can decline to the point of being threatened or endangered. This often happens due to high demand for certain species or their parts, such as ivory from elephants or fins from sharks.

2. Pollution and toxins: Pollution can have detrimental effects on species by contaminating their environment, food sources, or water. Heavy metals, pesticides, and industrial chemical waste can accumulate in the tissues of organisms, leading to health issues and reproductive problems. This can result in population declines and ultimately threaten the survival of the species.

It's important to note that these reasons are not exhaustive, and there can be several other factors contributing to the endangerment of a species. Each case requires careful study and analysis to determine the specific causes and develop effective conservation strategies.
